Will they allow me to add my AIM contacts? I don't use MSN Messenger and have no interest in it all

I tried Just Cause for the 360. Graphics were ok on it, and the stunt system was awesome. But the game was wayyyy too easy, the auto targeting made everything simplistic to incomprehensibility. I got it from Gamefly and damn glad I did, its not worth a buy. Don't waste your time on it. Justice League Heroes is next on my list.
